CHAIR.

Application filed March 10, 1924.. Serial No. 698,113.

To all til/[07R it may concern:

Be it known that 1, PETER SoHiioEDnR, a citizen of the United States,residing at Buffalo, county of Wright, and State of Minnesota, haveinvented certain new and useful Improvements in Chairs, of which thefollowing is a specification.

My invention relates to chairs and particularly to swinging chairs ofthe type wherein the chair proper is supported between a pair of sidebrackets.

lVith chairs of this type, it is more or less difficult to seat oneselftherein or to vacate the chair, owing to the free swinging thereof andthe fact that the usual foot rest e-X- tends so far as to interferetherewith. The object of my invention is to provide in a chair of theclass mentioned means for holding the chair stationary while entering orleaving the chair, which means can be readily operated by the occupanteither to release or look the chair as desired. A further object of myinvention is to provide a device as mentioned of such construction thatthe same will not readily become acci-' dentally locked. Other objectswill appear hereinafter.

With these objects in view my invention consists generally in a pair ofuprights or brackets, a chair swingingly mounted between the samc, saidbrackets being connected by a bar beneath the seat of the chair and alatch on the chair adapted to engage said bar to prevent the chair fromswinging. My invention further consists in a device as mentioned inwhich the latch is mounted upon a transverse bar beneath the seat andprovided with an actuating lever adjacent one side of the chair inconvenient position to be operated by the occupant of the chair. Myinvention further consists in a device as mentioned in which the latchis provided with cam faces for throwing the latch into inoperativeposition should it become accidentally thrown into operative position.

My invention further consists in various details of construction andarrangements of parts, all as will be fully described hereinafter andparticularly pointed out in theclaims. My invention will be more readilyunderstood by reference to the accompanying drawings forming a part ofthis specification and in which Fig. 1 is a front elevation of a chairembodying my invention, and

Fig. 2 is a side elevation thereof, a portion of one of the sidebrackets being broken away and the cross bar illustrated in section.

Referring now to the drawings, the base comprises a pair of horizontalside members suitably connected and braced. Each of said side membersisformed of a flat bar 1 which is twisted at 2 adjacent the forward andrear ends into a plane substantially at right angles to the body portionthereof and then bent under forming feet 3. The rearfeet 8 are connectedby a transverse bar 4 and the diagonally opposite feet are connected bycrossed brace rods 5. Extending upwardly from each of the members 1 is astandard 6. This is formed of a flat metal bar and a short distanceabove the base it is twisted as at 7 bringing the plane of the bartransversely of the structure. he upper ends of the standards 6 arecurved inwardly forming supporting arms 88, the upper edges of which arenotched as at 9 for a purpose hereinafter described. Brace rods 101Oconnect the standards 6 adjacent their upper ends, with the base members1, adjacent their forward and rear ends respectively. To complete arigid supporting structure, a transverse bar 11 is provided which hasits ends 12 curved at substantially right angles to the bar and rigidlysecured to the members 6. Beside serving to complete the rigidity of thesupporting frame, the bar 11 also serves as part of the chair lockingmeans as hereinafter described.

The chair proper comprises a seat 13, back 14: and foot rest 15 togetherwith suitable suspending members 16. The side frames of the seat andback are integral members formed of metal strips, bentas at 17 formingthe side seat members 18 and the side members 19 of the back. These arerigidly secured together at their upper ends by a cross bar 20; and theportions 18 are connected by a plurality of brace bars 21, which alsoconstitute supports for the seat 13 to rest upon. The seat 18 may be ofsheet metal or of any suitable material, and at the rear it is curvedupwardly as at 22, and has its upper end secured to a transverse bracerod 23. Any suitable back 14 is supported between the members 19. Thefoot rest 15 is supported upon a pair of side bars 2 1, which aresecured as at 25 to the forward ends of the side seat members 18 andthen curved rearwardly as at 26, forming arms for the chair, the rearends of which are secured as at 27 to'the members 19. A brace 28 fixed.betweenthe member-s24 supports the forets. The upper portion of saideyes rest in the notches 9 hereinbefore described.

Supported beneath the seat on depending brackets is a transverse rod 34:upon which is fixedly mounted a latch 35. Fixed to one end of the rod 34is a lever 36 which extends upwardly adjacent the outer side of one ofthe arms 26 and preferably between the same and a strap 87. It isobvious, therefore, that the latch may be readily operated by the lever36, which is in a position to be conveniently operated by the occupantof the chair.

The latch 35 is in a position to pass freely over the bar 11 when theformer is in the position shown in full lines in Fig. 2.; but so that itwill engage said bar when moved into the position shown in dotted lines.38 indicates a shoulder on the latch adapted to engage behind the bar 11to hold the chair from swinging when it is desired to enter or leave thesame. A cam face 39 is provided on the forward end of the latch, whichwill, should the latch be accidentally thrown into operative position,by engagement with the bar 11, throw the latch upwardly into inoperativeposition:

The operation of the device is obvious. When it is desired to lock thechair, the chair is swung backwardly and the latch depressed until theshoulder 88 engages be operative position,

hind the bar 11. It is then easy to leave or enter the chair. After thechair is occupied, the occupant, by means of the lever '36 may readilyrelease the chair. Should seat thereof adapted in one position to en-vgage said bar to prevent swinging of the chair, substantially asdescribed. I

2. A device as set forth in claim 1 further characterized by means onthelatch for throwing the same into inoperative position should the samebe accidentally moved into substantially as described.

3. A device as set forth in claim 1 further characterized by a cam faceon the end of the latch adapted to engage said bar and throw the latchinto inoperative position should the same he accidentally removed intooperative position, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PETER SCHROEDER.
